I'm running a plastic Gano and have been for about a year. I like the plastic window to be able to see the coolant when the engine is running. I don't like the plastic window because it's plastic. No problems so far, but you never know.
I like the screen. It works well to catch scale and little pieces of gasket sealer.
I don't like that I'm taking a perfectly good radiator hose with 2 connections, then cutting 1.5" out of it and adding 2 more connections.
I read on this forum that someone (sorry "someone", I forget your handle!) simply put the filter screen in their upper radiator neck. It is invisible, doesn't add connection/failure points, but also doesn't let you see inside.
